Microsoft brings five AI video models to Foundry through fal partnership

Developers building video into business applications have five more model options coming to Microsoft Foundry. Microsoft and fal announced the partnership on November 5, with the models rolling out in public preview as a first-party Azure service served by fal. The lineup covers generating video from written instructions and animating existing images.

Microsoft’s starting point is that video workloads need different tools. A team exploring a written creative brief may want several quick interpretations. A retailer animating an approved product image has a different starting point. The partnership is intended to let developers choose models for those steps and connect them with other capabilities in Foundry.

A selected portfolio, not fal’s full catalog

fal provides APIs—interfaces developers use to connect software—to more than 1,500 models across images, video, audio, 3D and generative worlds. This agreement brings a selected set of video models into Foundry, rather than that entire catalog. fal serves the models, which are sourced from the companies that build them.

• Kling v3 Pro supports image-to-video generation, native audio generation and custom elements. Microsoft positions it for applications that need control over how a still image becomes a moving scene.
• LTX-2.5 Fast and LTX-2.5 Pro both support text-to-video and image-to-video generation with synchronized audio. Microsoft describes Fast as optimized for rapid drafts and previews, and Pro as optimized for higher-quality final output.
• MiniMax H3 Max and MiniMax H3 Max Turbo are further-trained versions of MiniMax H3. Microsoft says they target closer adherence to prompts, aesthetics and performance when generating results. Its pricing table also lists reference-to-video support for H3 Max.

$0.08MiniMax H3 Max Turbo

Microsoft lists MiniMax H3 Max Turbo at $0.08 per generated video second at 1080p.

$0.13LTX-2.5 Fast

Microsoft lists LTX-2.5 Fast at $0.13 per generated video second at 1080p.

$0.17LTX-2.5 Pro

Microsoft lists LTX-2.5 Pro at $0.17 per generated video second at 1080p.

Resolution and sound change the bill

Microsoft’s launch pricing table labels its rates in dollars per generated video second. At 480p, MiniMax H3 Max starts at $0.05 and H3 Max Turbo at $0.025. At 720p, LTX-2.5 Fast is $0.09 and Pro is $0.12. Those starting prices cover different resolutions, so they are not a like-for-like comparison.

Higher-resolution output costs more within the listed options. MiniMax H3 Max reaches $0.16 per second at 1080p, while Turbo reaches $0.08. LTX-2.5 Fast extends to 1440p at $0.19 and 4K at $0.30; the table lists Pro at 720p and 1080p.

For Kling v3 Pro, the listed price changes with audio settings: $0.1232 per video second with audio off, $0.1848 with audio on, and $0.2156 with audio plus voice control. Sound is therefore a separate budget choice within that offering, not simply a feature included at one rate.

US hosting still requires a terms check

Microsoft says the initial portfolio is hosted in the United States and that Foundry is the first provider to offer a US-hosted Kling endpoint. That is a hosting claim, not a blanket assurance that every organization’s data requirements are met. Microsoft tells customers to review each model’s documented processing and storage terms.

For teams moving toward production, Microsoft points to evaluation, optimization, governance, security, monitoring and infrastructure capabilities supported by their selected offering. The qualification matters: customers need to check the support attached to the model they choose, rather than treating the five-model portfolio as one uniform service specification.

The rollout remains a public preview. Microsoft says more models are planned over time and that pricing will be added to its Azure pricing page in the coming weeks. Those are the next stated steps; the announcement does not give a date for general availability.
